AD8306ARZ

Analog Devices · Special Purpose Amplifiers · SOIC-16

AD8306ARZ from Analog Devices, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COM2 power_in Special common pin for the RSSI output.
2 VPS1 power_in Supply pin for the first five amplifier stages and the main biasing system; supply range is +2.7 V to +6.5 V.
3 PADL power_in Tie-down to the paddle on which the IC is mounted; grounded.
4 INHI input Signal input, HI or plus polarity; fully differential input with 1 kΩ input resistance and 2.5 pF input capacitance.
5 INLO input Signal input, LO or minus polarity; fully differential input with 1 kΩ input resistance and 2.5 pF input capacitance.
6 PADL power_in Tie-down to the paddle on which the IC is mounted; grounded.
7 COM1 power_in Main common connection.
8 ENBL input Chip enable, active when HI; the device is disabled at or below 1 V and fully enabled at or above 2.7 V with VS.
9 LMDR passive Limiter drive programming pin; resistor RLIM from this pin to ground sets the limiter output current, with a nominal bias of about 400 mV.
10 FLTR passive RSSI bandwidth-reduction pin; a capacitor between FLTR and VLOG lowers the RSSI corner frequency.
11 PADL power_in Tie-down to the paddle on which the IC is mounted; grounded.
12 LMLO output Limiter output, LO or minus polarity; open-collector output that may swing to 1.2 V below VPS2.
13 LMHI output Limiter output, HI or plus polarity; open-collector output that may swing to 1.2 V below VPS2.
14 PADL power_in Tie-down to the paddle on which the IC is mounted; grounded.
15 VPS2 power_in Supply pin for the sixth gain stage, limiter and RSSI output stage load current; supply range is +2.7 V to +6.5 V.
16 VLOG output Logarithmic (RSSI) output, nominally scaled 20 mV/dB.
